Dave Cottlehuber and I have been working on adding per-jail metadata feature to #FreeBSD.

Many thanks to the Jails Working Group for their feedback over the past few months. It's time for wider feedback. Dave's blog provides the details and some great examples: people.freebsd.org/~dch/posts/2...

An article I wrote has been published in the latest issue of the FreeBSD Journal: freebsdfoundation.org/wp-content/u.... It provides FreeBSD developers with details about a newly added feature that enhances the FreeBSD Test Suite’s parallelism. #FreeBSD

Forgot to create a #git repo first and discovered an Apple-like intuitive feature. Thank you, #gitlab . A simple push creates a new repo, instead of N clicks in a browser.

Target arch specifics may conceal a bug. Or how to deal with FreeBSD Netlink buffer overflow. Runtime environment specifics can be easily omitted when there are no dependencies on. But it's pity if they are forgotten when it's important to consider them. Just a reminder.
